A discussion a so much controversy, since we have several tendencies. 
I never used postwork, to not to be to include frame and signature, but I am not against postwork. 
The fact is that: If some details be just imported of other tools I don't consider the image as not pure Bryce. 
If Bryce be limited in some points (and he is) it justifies the import of objects that I cannot do with Bryce. 
Fantastic trabalhso exist signed by Vue, Daz, Bryce, Terragen among others that they were concluded largely by tools of retouchings, and nor for that they will leave of they be them same. 
To limit the use of Bryce or of any other tool it is to define your death. 
I will continue to be puristic until the day in that Bryce not to be permitted more to use him/it, but I won't stop eulogizing a good work where there was postwork. 
 
Excuse me for the translation.
